"Charging is not supported with this accessory"
When I charge my iPhone, I only use the cable that came with the iPhone. I have used compressed air to clean out the power socket. I have checked both power and headphone sockets and there is no water issue (i.e. no red marks).
My iPhone is only 4 months old, so I am willing to take it back under warranty if need be. But, I thought I would check here first.
As my first Apple product, I am not overly impressed with the brand thus far.
Thank you.
iPhone, iOS 4
